Electrical Equipment ManufacturingAuvergne-Rhône-Alpes, France2-10 Employees

Sylfen develops energy storage solutions that convert surplus renewable electricity into hydrogen, enabling local energy management and a carbon-free energy cycle. Its core technology is a high-temperature reversible system that operates as both an electrolyser and a fuel cell, leveraging patents from the CEA. The Smart Energy Hub is designed for sustainable buildings, providing a secure and connected way to store energy as hydrogen and later use it for power and heat or feed the local grid. When stored hydrogen is unavailable, the hub can generate power and heat from natural gas or biogas, and hydrogen can be used as a clean fuel for vehicles.

The company is based in Le Cheylas, in the Auvergne-Rhône-Alpes region of France, with roots as a Grenoble-based start-up. It operates with a small team and has expanded its footprint in Europe, including relocating its industrial operations to its historic site in Le Cheylas.
